Sep 14, 2016· ABSTRACTThe extractions of potassium value from feldspar via roasting and leaching route was studied with a focus on the effects of the roasting time, temperature, additives, and particle size. Sodium chloride and phosphogypsum (PG) were used as a source of chloride and calcium, respectively, and played the important role during the roasting of feldspar.

Preparation of potassium sulfate and zeolite NaA from Kfeldspar by a novel hydrothermal process. International Journal of Mineral Processing 2016, 155, 130135. DOI: / S. K. Jena, P. K. Misra, B. Das. Studies on Extraction of Potassium from Feldspar by Roastleach Method Using Phosphogypsum and Sodium Chloride.
Thermal decomposition of feldspar with the addition of CaSO4 and CaO has been reported [16]. Extraction of potassium from nepheline syenite by acid leaching and roastleach methods has been discussed [17]. The extraction of potash from Thailand soils by ionic exchangeable methods has been elaborately studied [18].
Further experimentation might, indeed, very essentially modify these conclusions, but they are given as having value to the extent that the work justifies: 1. Electrolytic methods for extracting potash from feldspar seem to be prohibitive in cost, because of the high power consumption per unit of .

Feldspar Processing General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).
Feldspars are formed from magma as a crystallize veins in igneous and metamorphic rock, most feldspars are deposited as sodium feldspar, potassium feldspar and mixed feldspars. Generally, the method through which feldspar can be extracted or mined is simple when compared with other mineral resources mining methods.
Beryllium Extraction Process Flowsheet Flotation offers the best means for recovering beryl in concentrate form. Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product.
The selective separation of gangue minerals requires acid proof equipment, which is described more fully in Flowsheet Study on Feldspar. The Lithium Ore Flowsheet Fatty acid or soap flotation of spodumene is one well established recovery method, but pulverized or ground particle surface conditions generally necessitate preflotation treatment.
The extraction of potassium from Kfeldspar via a calcium chloride calcination route was studied with a focus on the effects of the calcination atmosphere, calcination temperature and time, mass ratio of CaCl 2 to Kfeldspar ore and particle size of the Kfeldspar ore. The results demonstrated that a competing hightemperature hydrolysis reaction of calcium chloride with moisture in a damp ...
